Product Definition & Overview
The 108B Hidden Window is a high-end architectural exterior window system, serving as a critical component in "Minimalist" architectural design. Its core design philosophy is to "conceal the window within the wall." Through ingenious profile design and installation techniques, when closed, the majority or key components of the window are cleverly hidden within the wall or cladding. This creates a near-invisible traditional frame structure from both interior and exterior viewpoints, achieving perfect integration with the building facade and delivering maximized views and an ultra-clean visual aesthetic.
It is not merely a window but a comprehensive building facade system solution that integrates high performance, smart features, and aesthetic design.
Core Features & Advantages
Ultimate Aesthetics, Boundless Vision
Ultra-Narrow Sightlines: The concealment of sashes, hardware, and parts of the frame results in extremely narrow visible profiles, potentially achieving a "glass only, no frame" effect, maximizing the intake of natural light and outdoor scenery.
Unified Facade: Seamlessly integrates with interior and exterior décor styles without disrupting the wall's integrity. Particularly suited for designs that pursue pure spatial experiences like modern and minimalist styles.
High Performance & Specifications
Excellent Thermal Insulation: Typically employs multi-chambered thermal break aluminum profiles, combined with multiple sealing gaskets and LOW-E insulated glass units. The entire window's U-factor can be as low as 1.0 W/(m²·K) or below, meeting Passive House standards.
Superior Acoustic Performance: Robust profile structure and high-quality sealing systems effectively block external noise, with sound insulation performance reaching up to Rw ≥ 45 dB, providing a tranquil indoor environment.
Exceptional Wind Load Resistance & Water Tightness: Concealed drainage system design and sturdy profile structure enable it to withstand extreme wind pressures and effectively prevent water infiltration, ensuring safety and reliability.
Functionality & Smart Integration
Multiple Opening Methods: Offers various concealed opening options such as tilt & turn (inward), top-hung (outward), sliding, and folding to meet different ventilation needs.
Smart Home Compatibility: Can easily integrate motorized openers, rain sensors, wind sensors, smart locks, and other devices, enabling remote control, automatic ventilation, window closing, and other smart scenarios.
Easy Maintenance: Despite the concealed design, it often features removable glazing beads or concealed hinges, facilitating future glass cleaning and replacement.
Durability & Security
High-Strength Profiles: Manufactured from aerospace-grade 6060-T66 or 6063-T5 aluminum alloy, precision-extruded and surface-treated for high strength, strong weather resistance, and long service life.
Safety Glass Options: Standard tempered glass, upgradeable to laminated safety glass, bullet-resistant glass, etc., for enhanced security.
High-Performance Hardware: Utilizes dedicated concealed hardware systems with strong load-bearing capacity, smooth operation, and long-term durability.
Applicable Scenarios
High-End Residential: Villas, large apartments (penthouses), duplex penthouses where ultimate views and aesthetic effect are pursued.
Commercial Buildings: Luxury hotels, office buildings, brand flagship stores, clubs, art galleries, museums.
Modern Architecture: Opening vent sections in glass curtain walls, large floor-to-ceiling windows, skylights.
System Window & Door Projects: Iconic buildings with extremely high requirements for energy efficiency, sound insulation, and security.
Installation Process Overview
Embedded Installation Method: The window frame is pre-set into the wall structure during the construction phase. This method achieves the best concealment effect but requires extremely high levels of preliminary design and construction coordination.
Retrofit Installation Method: After wall completion, the window frame is enclosed and hidden by thickening the decorative finish layer.
Process: Measurement verification → Opening preparation → Install sub-frame/main frame → Leveling and alignment → Foam filler application → Install glazed sash → Hardware adjustment → Sealing (application of sealant) → Install interior/exterior decorative cover plates → Final cleaning and inspection.
Note: The final effect of a hidden window is 30% dependent on the product and 70% dependent on design and installation. It must be installed by a professionally trained team.
Summary & Market Positioning
The 108B Hidden Window represents the cutting-edge technical level and development trend within the current door and window industry. It transcends the functional positioning of traditional windows as mere "openings for light and ventilation," upgrading them into a "functional building envelope system" that enhances overall building value, shapes spatial aesthetics, and provides a healthy, comfortable environment.
Its target clients are designers, developers, and end-users with an ultimate pursuit of quality of life, architectural beauty, and performance. Although its initial investment cost is higher than that of standard windows, the value-added experience, energy efficiency benefits, and long-term durability it provides make it a highly valuable investment in high-end construction projects.
